Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The present invention designs a safe industrial control system based on a safe intelligent controller. The specific method is to embed the safety protection function from each unit of the system to realize the automatic control of the local industry and the data communication with the upper computer; Such as figure 1 As shown, it includes the PLC controller and the input and output modules. The input and output terminals of the PLC controller are connected to the designated equipment in the local industry through the input and output module. The control logic performs logical processing on the collected signals, obtains control signals, and feeds back the control signals to each designated device for automatic control.

[0022] In practical applications, the input and output modules support discrete and analog in...

Abstract

The invention relates to a safety industrial control system based on a safety intelligent controller. The system is composed of a PLC controller, an input and output module and an upper computer. ThePLC controller is the core of the whole system. An independently researched and developed industrial chip is adopted, and a security firewall and a security encryption system are arranged in the industrial chip. Safety protection is realized on an infected main body. An input and output module and an upper computer are matched to form a set of pure industrial control system with safety protection.A safety protection system is arranged in each link of the upper computer, the PLC and the input and output module, multiple protection is achieved, major accidents such as misoperation can be avoided even if one link is attacked, the other two links can be comprehensively verified and judged, fault processing is carried out, and safety measures are immediately taken to prevent accident expansion.

Description

technical field [0001] The invention relates to a safe industrial control system based on a safe intelligent controller, belonging to the technical field of intelligent controllers. Background technique [0002] Industrial control systems are widely used in various industries. From a broad perspective, any occasion where industrial control equipment can be applied can be called an industrial control system. Whether it is manufacturing or processing production, it is inseparable from the industrial control system. Especially in critical infrastructure, such as chemical industry, water conservancy facilities, financial services, commercial facilities, defense industry, food industry, communications, emergency response, government facilities, key manufacturing, energy, public health, water treatment , information technology, nuclear reaction facilities, transportation systems and other important sectors that support modern society. It is precisely because of the importance of...
